Hazards Analysis Cause Records

Hazards Analysis Cause records store details on the cause of a particular event or condition within a process. This topic provides an alphabetical list and description of the fields that exist for the Hazards Analysis Cause family. These fields appear on the Hazards Analysis Cause datasheet, unless otherwise specified. The information in this table reflects the baseline state and behavior of these fields. This list is not comprehensive.

This family is enabled for site filtering, which means that records in this family can be assigned to a specific site, and will then only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. See the Site Filtering section of the documentation for more information on using this feature.

Field	Data Type	Description	Behavior and Usage
Cause Comment	Text	Comments about the cause.	None
Cause Description	Text	A detailed description of the cause.	None
Cause Frequency (per year)	Number	A numeric value that represents the number of times per year the cause may occur.	This field is disabled and populated with the default value of frequency specified in the Initiating Event record based on your selection in the CCPS Cause Type field.
Cause ID	Character	A brief description of the cause.	This is a required field.
Cause Number	Character	A set of three numeric values, separated by decimal points, which represents the location in which the Cause appears in the hierarchical view of the components in the Systems/Nodes.	This field is disabled and populated with a set of three numbers, separated by decimal points (e.g., 2.1.1). The first two numbers correspond to the value that exists in the What If Number field in the What If or the Deviation/Guideword Number field in the Deviation to which the Cause is linked. The third number is the value that exists in the Sequence Number field in the Cause.
Cause Type	Character	The type of cause.	This field contains the description of the System Codes that exist in the MI_HAZOP_CAUSE_TYPE System Code Table. You can choose from the following baseline values: Equipment Failure Human Error Process Upset Flooding Lightning Power Loss Terrorism
CCPS Cause Type	Character	The type of cause as defined by CCPS.	This field is populated by the value in the Initiating Event ID field of the Initiating Event records. When you create a LOPA from a cause-consequence pair in Hazards Analysis module, the Initiating Event Type field in the LOPA is disabled and automatically populated with the value in the CCPS Cause Type field.
Equipment Entity Key	Number	The Entity Key for the Equipment whose Record ID appears in the Equipment ID field.	This field does not appear on the datasheet.
Equipment ID	Character	The ID of the Equipment that is linked to the Cause through the Safety Analysis Has Equipment Relationship family.	This field contains a button, which you can select to link an Equipment to the Cause.
Functional Location Key	Number	The Entity Key for the Functional Location whose ID appears in the Functional Location ID field.	This field does not appear on the datasheet.
Functional Location ID	Character	The ID of the Functional Location that is linked to the Cause through the Has Functional Location Relationship family.	This field contains a button, which you can select to link a Functional Location to the Cause.
Sequence Number	Number	A numeric value that represents the position in which the Cause appears in the hierarchical view of the components in the System/Node, relative to the other Causes that are linked to the same Deviation or What If.	This field does not appear on the datasheet.
